I got this error message- (Can't locate IO/Scalar.pm in @INC (@INC contains: /opt/rocks/lib/perl5/5.8.8/....)) when I run a program. However, the Scalar.pm is located in the '/opt/rocks/lib/perl5/5.8.8/IO/' directory and this directory is in the array @INC. Does anybody know what's wrong with it?

Well, if there is no error message then I am not sure what the problem is. Are you using Windows? Do you have mopre than one install of Perl on Windows? That is a bad idea and can lead to problems. -------------------------------------------------
